Size Conversions, Life size and Printable Size Chart
Click the Lifesizer to view dimensions in life size. If your screen is already calibrated, the chart will display in Life Size, otherwise you will be prompted to calibrate your screen. You'll only need to calibrate once, and if you're on an iPhone or iPad, no calibration is needed, it's done automatically.
